I would like to thank the following people for their assistance in this project, Mr. A. G. W. Robertson my project supervisor for his assistance, guidance and the encouragement he gave me throughout this project, Dr. P. E. Kopp for pointing me in the right direction on how to solve overdetermined linear systems, Lorna Dewar for her assistance in taking the phantom images and all those people, who gave up their spare time to register the image set. Finally, I want to express my special thanks to my mother. Without her constant encouragement and support over the past two decades, none of this would have been possible.
